Hello!

Unfortunately I'm not sure if I'm getting the expected results. I'm ran gz sim multi_lrauv_race.sdf on the terminal and the following screen popped up:

Although, when I click play a very strange behaviour happened:

My CPU/GPU/Memory usage were also all lower than 40%.

Also, when I launched the world the following error messages appeared, I dunno if it is correlated:

libEGL warning: egl: failed to create dri2 screen
libEGL warning: egl: failed to create dri2 screen

Please let me know if I should do any additional testing.

yes it's affecting others as well. There is a pull request to fix the issue: gazebosim/gz-sim#2111

[matosinho]

How can I test the pull request with binary install? I'm planning to go for source install later and I could definetely test, but for binary I dunno how to do it.

I would say to test it out with the source install. As far as I know, there shouldn't be any other way to try out a PR.

[Voldivh]

Hey @matosinho did you manage to try out the fix from the PR?

[matosinho]

Not yet... Since the mentioned pull request to fix was accept, if I re download the binaries, I should be able to get the version with the implemented PR, correct?

[azeey]

No, we haven't released binaries for gz-sim yet. You'd have to build from source or wait till we make another release.

[Voldivh]

I tried out the fix and works just fine. Since the PR have been merged, I'll be closing this issue.
